Add explicit deposit/withdrawal path limits and gas accounting

[grantfox-oss]

Complex escrow operations can consume unpredictable Soroban resources. Without explicit deposit/withdrawal limits or gas accounting, transactions can fail unpredictably or expose denial-of-service vectors.

Affected areas: app/contract/contracts/Folder/src/escrow.rs, app/contract/contracts/Folder/src/lib.rs, app/contract/contracts/Folder/src/error.rs, app/contract/contracts/Folder/src/test.rs.

Implementation scope:

• Define maximum supported token counts, arbiter counts, and fee recipient counts for deposit and withdraw paths.
• Add explicit gas estimates and reject requests that exceed safe bounds.
• Emit contract errors for oversize payloads or resource limits.
• Add tests for limit boundaries and large input rejection.

Acceptance criteria:

• Deposit and withdrawal operations enforce bounded parameters and fail with clear errors when exceeded.
• The contract reports predictable gas usage for supported payload sizes.
• Documentation includes the supported contract limits.
